How can I determine the source of excessive garbage collection in my HTML5 javascript game?

Question

How can I determine the source of excessive garbage collection in my HTML5 game?

Here's the result of a heap snapshot I took in chrome:

Example, please? How can we answer if you don't tell us anything that's going on? — bfavaretto, Sep 05 '12 at 02:59
http://stackoverflow.com/questions/864516/what-is-javascript-garbage-collection Perhaps a relevant question you may look into? Having a good understanding of what garbage collection helps. — aug, Sep 05 '12 at 03:00
What do you mean by "excessive"? Too-frequent collection? Could you describe some symptoms to explain why you think your issue is related to garbage collection at all? — nnnnnn, Sep 05 '12 at 03:34
@nnnnnn: Sure -- looking at the memory timeline in Chrome shows the characteristic zigzag pattern of heavy garbage collection. Eventually, the garbage collection starts taking on the order of a second to complete, resulting in an unacceptable pause. Qiao essentially answered my question (hence the screenshot I posted), though I am hoping for more insight into the problem. For example, how can I get to the bottom of where all the Array objects are coming from? Is there some way to find out where they were created? — shino, Sep 05 '12 at 03:51
